Industrial Cables Multi-Core Flexible Cables

318TQ to BS 6500

Application and Description
318TQ to BS 6500 cables can be used either in dry, humid or wet places or in contact with oil or grease, in weather conditions and under weak mechanical stress, they are suitable for power supply to small appliances in
industrial plants, machine shops, heating plates, portable lamps, farming equipment etc. They are also
suitable for caravans and camping equipment. 318TQ is equivalent to harmonized code H05BN4-F.

Cable Construction

Fine bare copper strands
Stranding to BS 6360 Class 5 or IEC 60228 Class 5
